General System Information 3.1 Overview Cobham introduces the Broadcast industry’s first AVC / h.264 COFDM wireless Camera-Mount transmitter for transport of Standard (SD) plus High Definition (HD) audio /video streams. The Messenger 2 Series (M2) product line incorporates many of the original “Messenger” product line capabilities with two major upgrades. The M2 series incorporates the AVC compression technology with one frame delay which replaces the MPEG-2 compression, and they cover all the SD and HD formats up to 1080P. One of the biggest problems encountered in the transition from an analog to a digital A/V platform has been the inherent digital coding delay that in some digital systems are 1.5 seconds or more for HD. The M2T-C employs a specially designed ‘Ultra-Low Delay’ coding technology, which provides 44mS (~ 1 frame) end-to-end system delay when using Cobham’s AVC Decoder. This ensures that the picture you see is what is happening now; crucial for applications such as sports and news coverage! The internal Data Return Link (DRL) provides a bi-directional serial data path (up to 115.2 kBaud) that can be used for a variety of remote control and communications requirements including control of all of the M2T operating parameters and enables the addition of camera control, audio communication and many other special features. This manual provides information on how to operate the M2T-C as well as pertinent technical information related to the overall system. Refer to the model identifier (on-line document, 100MNI0063 - latest revision) at Cobham website, http://www.cobham.com/tcs, for available frequency and power configurations along with options. 3.2 Key System Features Built–In AVC / h.264 Encoder SD and HD formats up to 1080p Low Power Consumption (16.5 Watts) Low System Latency (1 frame with Cobham AVC Decoder) Local Control plus Data Return Link User Data Support AES 128/256 Bit Security COFDM Modulation w/Local Control Output Frequency: 1 to 7 GHz (In–Bands) High-Throughput 4 K option for maximum link performance Rugged and Compact Portable Design Companion COFDM receiver with Maximal-Ratio Pre-Detect Diversity reception 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 8 of 55 www.cobham.com/tcs 3.3 Theory of Operation The Messenger 2 Transmitter – Camera-mount (M2T-C) accepts Standard Definition (SD) or High Definition (HD) 4:2:2 digital video or analog SD video and analog stereo audio inputs (Mic or Line level). The video is compressed according to the Advanced Video Compression (AVC) /h.264 specifications. The low-latency AVC Encoder supports the Baseline Profiles with resolutions from 480 to 1080 with support for either interlaced or progressive formats. The audio is compressed using MPEG layer II compression. Low rate user data up to 38.4K Baud can be optionally supported. The audio, video and user data packets PES streams are multiplexed with basic service data to indicate the service name. The stream can be scrambled with AES scrambling system to provide protection in sensitive applications. A complete Cobham Messenger 2 Camera Link for wireless camera application includes the Messenger 2 Transmitter – Camera mount (M2T-C), the Messenger Smart Receiver (MSR), a Messenger Two Decoder (M2D) and one or several external Block Down – Converters (BDC), as shown in the figure 1 below. The M2T-C provides professional Audio/Video (A/V) interfaces and processing. All versions of the Messenger Digital Link family use a robust digital modulation system known as Coded Orthogonal Frequency Division Multiplexed (COFDM) that provides frequency diversity and powerful Forward Error Correction (FEC) algorithms. The Messenger Smart Receiver (MSR) provides for Spatial Pre-Detect Maximal-Ratio Diversity Combining of up to six independent antennas per MSR to increase the Signal Strength, Signal-to-Noise Ratio and combat short delay spread multipath reflections found in indoor environments. There is a dramatic increase in the operating threshold when multiple high-gain antennas and Block DownConverters (BDC) are used with the MSR, greatly enhancing link robustness when operating at the high data rates as required for HD transmission. The MSR outputs a transport stream simultaneously over ASI and SPI interfaces. External Audio/Video/Data MPEG Decoders are sold separately that support HD or SD AVC Decoding. The 4 K HIGH-THROUGHPUT OPTION enables user-selectable options to set bandwidths from 6 MHz to 16 MHz and to double the throughput of our standard M2T (Up to 63 Mbps!). Using 4 K carriers and the 16 MHz bandwidth, the link can support HD operation with > 12 Mbps while running QPSK and ½ FEC. This increases link robustness and provides an additional 13.5 dB increase in link margin (>4.7 x increase in operating range!) for the same throughput rate in a standard HD MPEG-2 DVB-T system! With the HIGH-THROUGHPUT OPTION you can run with fully DVB-T compliant 2 K carriers and bandwidths of 6, 7, or 8 MHz. When switched to 4 K carriers user can select 12, 14 or 16 MHz bandwidth. The 4 K HIGH-THROUGHPUT OPTION is also useful when transmitting multiple video streams through one transmitter. This option requires a special receiver configuration. Please contact Cobham Sales for additional information. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 9 of 55 www.cobham.com/tcs 4. Initial Checkout 4.1 Included Items The standard M2T-C kit includes the following items: M2T-C unit. M2T-C full breakout cable (Cobham part number 780-C0291) (Power, A/V input, User Data, Control interfaces) NOTE: Based on customer application Cobham may deliver a receiving system, additional cables and antennas. Contact Cobham for further information. The device is pre-configured by Cobham prior to shipment (based on customer requirements), thus is ready to work “right out of the box”. 4.2 Getting Started Prior to installing a M2T-C unit into the desired target environment, an initial checkout should be performed to ensure proper operation of the unit. The initial checkout consists of configuring a basic MT2-C link. Figure 1 shows a basic standard M2T-C wireless link configuration. (NOTE: MSR, M2D and D/C units and their associated hardware are sold separately). The steps necessary to setup the configuration shown in Figure 1 are shown below. High throughput optional M2T-C require additional hardware (which includes two MSRs, a DDP plug in card and a combiner). Figure 1 – Basic M2T-C Link Setup 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 10 of 55 www.cobham.com/tcs 1. Install Omni-directional antennas onto the M2T-C transmitter RF output port and at the receiver end Down-Converter(s) RF input port. Note: Transmitters should not be powered on without a load attached to the RF output connector. The internal PA could be damaged. 2. Attach an SDI video source to the M2T-C SDI BNC (J1) video input. A composite signal can also be applied to the M2T-C BNC J6 composite in connector however keep in mind that the video source must match the configuration group setting of the transmitter. Refer to section 5.4.2.1.4, “TX HD Enc Setup” configuration group display, section 6.1 and section 6.4.2 on the selection of the transmitter (M2T-C) groups, the use of the keypad and the navigation of the menus. 3. The MSR should be pre-configured from the factory (refer to the Cobham web site for the online manual). In short ensure the MSR is powered, has a cable from the ASI out to the decoder ASI input, that each tuner has a RF cable which runs to each block down converter (each tuner is provided power either through the MSR or locally) and is set to the same RF frequency as the transmitter. 4. Attach a video cable from the video out of the decoder to a video monitor. Refer to the decoder’s operational manual for proper setup. 5. Provide power to the M2T-C (+12 Volts) by switching on the power switch to the down position. This is a three-position switch. The down position allows an IDX or AB battery to power the unit. In the up position external power through the DB-15 connector (J5) can be provided to power up the unit. In the middle position the unit is off. The LCD backlight display will light up immediately upon power although no meaningful characters are displayed until the unit has fully initialized (approx. 20 seconds). 6. Turn on the video source and video monitor equipment. 7. After approximately 20 seconds the link should be established and video provided by the source should be displayed on the monitor. An optional computer with the MSR control software installed can be used to monitor the receive parameters such as BER, MER and Signal to Noise. This connection can be through the USB or RS232 port. The initial checkout described above is simply to check the basic video operation of the M2T-C unit. For further details on monitoring and controlling the M2T-C using Cobham’s MS Windows-based M2TC Configurator software program, see Section 6.4. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 11 of 55 www.cobham.com/tcs 5. Hardware Overview The basic M2T transmitter configuration is outlined in this section: Figure 2 – M2T-C Connectors 5.1 M2T-C Connectors There are eight connectors located on the M2T-C unit as shown in Figure 2. They are for interfacing the RF, DRL, SD/HDSDI/ASI, Audio, Video (component & composite), and Control signals. There is also an on/off power switch shown in Figure 3. 5.1.1 RF Output (J7) The M2T-C uses a female ‘N’ Type bulkhead connector for its ‘RF Output’ port. The antenna is attached here. Note: Transmitters should not be powered on without a load attached to the RF output. Doing so could damage the internal Power Amplifier (PA). 5.1.2 DRL Antenna Port (J8) The M2T-C uses a female SMA bulkhead connector for the DRL (Data Return Link) port. The DRL allows remote control of M2T-C operating parameters and the ability to control external devices. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 12 of 55 www.cobham.com/tcs Features like camera control, tally, pan and tilt control can be accomplished using additional third party hardware. This is an optional module. 5.1.3 SD/HD SDI_ASI IN (J1) A female BNC connector is provided for SD-SDI or HD-SDI video input streams. The input bit rate is 270 Mbps for SD and 1.485 Gbps for HD. In addition this input connector can be used as an input for ASI DVB compliant Transport Streams. See section 6, software overview, for details on Input Modes. The section explains how to switch from SDI IN to ASI IN using the Cobham Tactical Communication & Surveillance M2T Configurator. 5.1.4 ASI Out (J2) A female BNC connector is provided for DVB-ASI Transport Stream Output. The output bit rate is 270 Mbps. This transport stream does not include the SI tables, User-Data, or AES encryption which is added later in the processing chain. 5.1.5 Audio inputs (channels 1 and 2) (J3 & J4) Two female XLR connectors are provided for balanced 600 Ohm audio input (see section 5.2 for other audio input configurations). The audio signal can be set for line or mic level. If audio is not used it’s a good idea to disable audio inputs, either through the front panel keypad (see section 5.4.2.1.6) or using Cobham M2T-C Configurator (see section 6.4.5). 5.1.6 Composite Video input (J6) A female BNC connector is provided for composite video input. For this input to function correctly the transmitter must be set up for SD mode by selecting the correct video Group using either the PC control application software (Cobham M2T-C Configurator, see section6.4) or the front control panel (see section 5.4). 5.1.7 Control & Optional Interfaces (J5) The Control connector is a female, DB-15. It is used to provide the interface for USB signals (control and monitoring), external power, and the Pb (blue) and C/Pr (red) portions of component video (the composite input, J6, is used as the “Y” portion of component video). The C/Pr is also used as the “C” portion of S-Video (also using the composite input, J6, as the “Y” portion of S-Video). Additionally, the bi-directional DRL’s external two wire RS-485 connections are provided. Note that the multi-drop RS-485 interface can be used to access multiple devices. This includes RS-232 devices using external third party conversion modules. A Cobham external break out cable (# 780C0291) is available which incorporates the pin outs for the I/O connector as shown in Table 1.

Other configurations are possible and they are listed below, however any changes to the default must be made at the factory since it involves opening up the transmitter. Possible configurations include: Balanced 600 Ohm impedance (default configuration) Balanced high input impedance (>2 K) Single ended high input impedance (>2 K) Single ended 600 Ohm impedance 5.3 Power Switch The power switch is a three-position switch (Figure 3). In the down position power is sourced from a battery (IDX or AB). In the up position external power is provided through the DB-15 connector, J5, pins 13 (GND), 14 and 15 (+12 Vdc). When the power switch is in the center position the M2T-C is off. See Figure 3. The backlight of the LCD serves as a power indicator and lights immediately upon power up. It takes approximately 20 seconds for the transmitter to fully initialize. Figure 3 – Local Control and Power 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 14 of 55 www.cobham.com/tcs 5.4 Front Panel Control Keypad & LCD Display The Front Panel Control consists of a LCD and a four-button keypad. (Figure 4) Figure 4 – Front Panel Control Upon power up of the transmitter the LCD backlight lights (indicating to the user power has been applied), displays “ TX is booting….wait, then very briefly displays the M2T-C logo and the software major release date such as ‘July23 2009 11’ before jumping to the opening RF Frequency Display. Keep in mind because of the complexity of the unit there are many parameters that can be changed only by using the PC GUI control software (Cobham Configurator) which is explained in section 6.4. Note: The PC GUI control software (see section 6) may interfere with requests made from the LCD front panel controls. Hence, before using the LCD front panel controls ensure the PC GUI software is disconnected from the transmitter. Also note the following menu structure corresponds to the latest firmware installed into the transmitter. Your display may vary a little depending on the firmware installed at the time of the transmitter build. Refer to earlier versions of this manual for other menu structures. 5.4.1 LCD Menu The following items can be accessed through the keypad using the and , , and the arrows. The Main Menu consists of the following displays: • TX RF FREQ • VIDEO LOCKED (status screen) • TX HD ENC SETUP • TX POWER LEVEL • ENTR DETAIL MENU • TX AUDIO • TX AUDIO GAIN (if available) The Detail Menu (sub-menu of less used functions) consist of the following displays: • TX CHANNEL MODE 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 15 of 55 www.cobham.com/tcs • TX DELAY MODE • TX RF ON/OFF • TX LCD Backlight • EXIT DETAIL MENU The menu flowchart trees are shown in Figure 5 below. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 16 of 55 www.cobham.com/tcs Figure 5 – Default Menu Tree LCD Front Panel Control 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 17 of 55 www.cobham.com/tcs 5.4.2 Explanation of the LCD Displays When the unit is first powered up the LCD backlight lights up, serving as a power indicator; however, no meaningful characters are displayed until the unit has fully initialized which takes approximately 20 seconds. 5.4.2.1 Main Menu Note that most of the displays in the main menu (except for the VIDEO LOCKED/UNLOCK status display) will time out after about 10 seconds. After that time the LCD automatically jumps to the TX RF FREQ display. 5.4.2.1.1 Opening Display Upon power up the LCD very briefly displays the M2T-C logo and software version number and then jumps to the opening RF Frequency Display. 5.4.2.1.2 ‘TX RF FREQ’ Display The TX RF FREQ display shows the current RF frequency setting in MHz. The frequency can be changed with the UP or DOWN arrow. Changes will not take place until the ENTR key is pressed. As the frequency is changed the “2250.0 MHz” portion of the display flashes indicating a change is taking place however if the ENTR key is not pressed after approximately 10 seconds (or the CTRL key is pressed) the frequency resets itself to the original frequency. The RF frequency displayed is in the band that is purchased, for example, S2 band, C1 band, etc. and may not reflect the numbers shown in the examples below. IF for any reason the RF is disabled (intentionally or not) or if the Video becomes unlocked, this display will indicate to the user by flashing “RF IS OFF”, or by flashing “VIDEO UNLOCK”. This is a very useful indication to let the user know that perhaps the video input to the transmitter is not connected or maybe the RF was turned off and hasn’t been turned back on. The next display is presented with the press of the CTRL key. 5.4.2.1.3 ‘VIDEO LOCKED/VIDEO UNLOCK’ Display This screen shows the current status of the video if is locked or unlock and what video format the transmitter has been set to. It will display on one line, alternating between parts of the message the transmitter video setup format such as “TX Video set to …..SDI 1080i 29.97. Keep in mind this is only a status screen. Video formats (associated with configuration groups) cannot be changed here. If a change is desired it must be done in the next display ‘Tx HD Enc Setup’. The next display is presented with the press of the CTRL key. 5.4.2.1.4 ‘Tx HD Enc Setup’ Configuration Group Display The Tx HD Enc Setup display shows the current configuration group selected and within this display a different configuration group can be selected. A group number (GP1 in this example) is associated with each group. The video frame size (1080i) and video frame rate (29.97) in this example is part of the title for this group. There are other very important parameters associated with each configuration group which are factory defaulted (Appendix B -) The parameters can be viewed, changed and saved using the Cobham 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 18 of 55 www.cobham.com/tcs Configurator (as explained in section 6) along with the group titles. Group selection can be changed with the UP or DOWN arrow. The “TX” portion of the display flashes indicating a change is in process but does not take effect until the ENTR key is pressed. Appendix B lists the default Groups that the M2T-C supports. NOTE: Keep in mind the RF frequency (along with several other important parameters) is tied in to the configuration group. Hence changing a configuration group will also change the RF frequency. Thus there are two ways to change the RF frequency, directly from the TX RF FREQ display or by changing the configuration group from the TX HD Enc Setup display. The next display is presented with the press of the CTRL key. 5.4.2.1.5 ‘ENTR DETAIL MENU’ Display Pressing the ENTR key directs the user to the detail sub-menu where the TX Channel Mode, TX Delay Mode, TX RF ON/OFF, and the TX LCD Backlight screens are accessed (see section 5.4.2.2 below). Pressing the CTRL key takes the user to the TX Audio screen still in the main menu, The next display is presented with the press of the CTRL key. 5.4.2.1.6 ‘Tx Audio’ Display The current audio setting is displayed here. In addition audio selections can be changed by use of the UP or DOWN arrow. The three selections are: “OFF”, “Analog Audio” or “SDI” audio. Keep in mind SDI audio selections have two channels associated with each selection. The choices are Ch1-2, Ch 3-4, and so on up to Ch 15-16. Based on the parameters of the current embedded audio in the SDI stream, that is which audio groups and which channels are active, the user can select two channels from the stream. If the ‘Tx Audio’ display shows that audio is “OFF” or “SDI” audio is active then the press of the CTRL key jumps to the opening TX RF FREQ screen. There is no ‘Tx Audio Gain’ display associated with either of these selections. The next display is presented with the press of the CTRL key if Analog Audio is active. 5.4.2.1.7 ‘TX Audio Gain’ Display (if available) The TX Audio Gain display shows the current gain setting for analog audio only. This menu is not available if audio has been turned to ‘OFF’ or if ‘SDI’ audio has been selected. In this example it reads “50”. The range is from 0 to 100. Pressing the UP or DOWN arrow will either increase or decrease the current value (value eventually wraps around). The gain value entered takes place immediately. The next display is presented with the press of the CTRL key, which is the return to the TX RF FREQ display. 5.4.2.2 DETAIL MENU Unlike the main menu displays these displays do not time out. The user needs to manually get back to the main menu (by using the key pad) or on a power cycle the transmitter will default to the TX RF FREQ menu. 5.4.2.2.1 ‘TX Channel Mode’ Display The TX Channel Mode display allows customers to choose different channel plans: manual channel mode (default), user defined, new BAS (S2 band only), and old BAS (S2 band only). 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 19 of 55 www.cobham.com/tcs Pressing the UP or DOWN arrow toggles the display between these plans. The “TX” portion of the display flashes as a change takes place (up or down arrows are pressed) but does not take place until the ENTR key is pressed. Once a pre-defined channel plan is selected the channels can then be selected from the TX RF FREQ display or by selecting a different configuration group (under the TX HD Enc Setup display). A more detailed description of the channel plans is explained in section 7.3.6.2.1.1, the software overview. The next display is presented with the press of the CTRL key. 5.4.2.2.2 ‘TX Delay Mode’ Display The M2T-C transmitter encoder is associated with two different delay modes (keep in mind that the type of decoder used can also add delays): Normal – this mode gives the best picture but the delay is longer than the ultra-low mode. Ultra-Low – this mode is the default which can only be used with Cobham Tactical Communication & Surveillance M2D HD decoder and offers the fastest <44 mS system latency. Pressing the UP or DOWN arrow toggles the display between these two modes. The “TX” portion of the display flashes indicating a change is in process but does not take effect until the ENTR key is pressed. The next display is presented with the press of the CTRL key. 5.4.2.2.3 ‘TX RF’ Display This display allows the user to turn OFF the RF or if the RF is OFF already then to turn it back ON. One of four options can be selected by using the UP or DOWN arrows. The options are: • RF OFF w/o saving to EEPROM. The RF is turned OFF, but on the next power cycle the transmitter RF mode is determined by the previous saved state. • RF OFF w/saving to EEPROM. The RF is turned OFF and on the next power cycle of transmitter the RF remains OFF. • RF ON w/o saving to EEPROM. The RF is turned ON and the next power cycle of the transmitter RF mode is determined by the previous saved state. • RF ON w/saving to EEPROM. The RF is turned ON and on the next power cycle of transmitter the RF remains ON. The next display is presented with the press of the CTRL key. 5.4.2.2.4 ‘Tx LCD Backlight’ Display The TX LCD Backlight display shows the current status of the backlight, on or auto. Pressing the UP or DOWN arrow toggles the display between ON or AUTO. Change does not take place until the ENTR key is pressed. Pressing any key on the keypad activates the LCD backlight automatically for approximately 20 seconds if the backlight is set for AUTO. The backlight also lights immediately upon power up serving as a power indicator. The next display is presented with the press of the CTRL key. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 20 of 55 www.cobham.com/tcs 5.4.2.2.5 ‘EXIT DETAIL MENU’ Display This display allows user to exit the detail menu and return to the main menu. Pressing the CTRL key takes you back to the TX Channel Mode display which is a continuation of the detail menu. Pressing the ENTR key takes the user to the main menu TX RF FREQ display. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 21 of 55 www.cobham.com/tcs 6. Software Overview 6.1 Product Control & Status Monitoring Approach Cobham Tactical Communications & Surveillance transmitters provide programmable presets or set-up groups that can be configured through special programming software by administrators. Set-up “Groups” are selected by the user through either the transmitter’s group select switches on the side of the transmitter or remotely through the M.S. Windows Application programs (see section 7.3.1, software overview below). The M2T allows 20 set-up groups. Administrators define the set-up groups for specific applications. Each set-up group (see appendix B for default configuration group set-ups) completely defines all of the transmitter’s set-up parameters including Center Frequency, output RF Power Level, Modulation Parameters, Video, Audio, User Data and Encryption. Each set-up group can be completely different from any other group. Field personnel can select specific set-up groups via pre-determined guidance from the administrators. Matching the transmitter operation to the receiver operation is as simple as selecting the same set-up groups. For example: If the transmitter is set to preset #19, then the receiver needs to be set to preset #19 for them to operate together. It should also be noted that Cobham Tactical Communications & Surveillance transmitters are designed to remember the last set of saved settings and will always power-up in the saved set-up group settings that it had prior to shut-down. A PC based application (MS Windows) called the Cobham Tactical Communications & Surveillance M2T Configurator has been developed to provide in depth control, configuration and monitoring of the transmitter. This Graphical User Interface (GUI) program provides the end user with a straightforward way to interface with the M2T. During normal operation the M2T Configurator GUI does not need to be active and can be disconnected from the transmitter unit. 6.2 System Requirements The Cobham Tactical Communications & Surveillance M2T Configurator program has been developed and tested on Windows XP SP3, Windows Vista (32 and 64 bit), and Windows 7 (32 and 64 bit). Although the Cobham Tactical Communications & Surveillance M2T Configurator program may work properly on other operating systems, no support or assistance can be provided with regards to other operating systems. 6.3 Installation The following instructions outline the installation process for the Cobham Tactical Communications & Surveillance M2T Configurator program: 1.

When the M2T Configurator program is launched, the screen shown in Figure 6 is displayed. The user should first select the serial port their computer is connected to via the Serial Port Selector and Status region. Use the pull down menu to select a port. If the selected serial port is valid, the gray-colored status box will show ‘Ready’. Figure 6 – M2T Configurator The M2T also works with a USB connection (correct drivers need to be loaded which are provided on the CD). The computer maps the USB port to an active RS-232 COM port. You need to check which port the computer has mapped the RS-232 COM port (this may also change each time the transmitter is booted). Check the port by right clicking on “My Computer” icon and select “properties”. Under the “Hardware” tab select “Device Manager” button (you can also get to the same menu from the “Control 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 23 of 55 www.cobham.com/tcs Panel” under the “Start” button and click on the “System” icon). Then select the “Ports (COM & LPT)”. Under this section the computer shows which port has been mapped to which COM port. Note this COM port and use it when selecting the COM port under the “Serial Port Selector and status” of the M2T Configurator software. The Device Selector region allows the end user to select from various devices. Presently the existing selections are reserved for future devices. To start the application, select the ‘M2T’ check box in the Device Selector region. Once the box is selected, the opening screen as shown in Figure 7 appears. The M2T Configurator program contains function buttons and configurable settings. The following sections explain, in detail, the various options available.

Here the Administrator defines the user’s rights by clicking on the radio buttons under “User”. They are briefly explained below: 1. The “Main Access Control” (see Figure 11). The parameters associated mostly with the video and RF setups of the transmitter are located under this tab (elements the user would normally see from the front page of the GUI as shown in Figure 7 above). 2. The “Encoder Setup Access Control” (see Figure 12). The encoder parameters such as Video delay mode and GOP length are listed here. 3. The “TS PID Access Control”(see Figure 13). The various PIDs which are changeable are listed here. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 25 of 55 www.cobham.com/tcs 4. The “Scrambling and User Data Access Control (see Figure 14 & Figure 15). If these options are not available then the message in Figure 14 appears. Otherwise the parameters associated with scrambling and user data are listed as shown in Figure 15. 5. The “Others Access Control” (see Figure 16) contains various other parameters such as ‘power mode’, ‘spectrum inversion’, etc. 6. The “Admin Password” (see Figure 17). The administrator password can be changed in this window or reset back to the default which is “admin”. Before exiting any of the ‘Access Control‘ windows, ensure to click on the “Update” and then “Save” buttons; if the intention is to save the changes. The “Update” button only implements the changes until the next time the transmitter is powered cycled. After making changes return to the main screen, under the “Configuration” menu select “Logoff” to exit the Access Control windows.

Be aware that it may take approximately 30 seconds for the transmitter to fully initialize. “Enable All” Button: Clicking on this button enables all the check boxes on the screen. This operation is done to prepare all the fields to be written to (or read from). Alternatively, the end user can individually select a given field by using the mouse and clicking its corresponding check box (individual selection of a given field speeds up the read write operations significantly). “Disable All” Button: Clicking on this button disables all the check boxes on the screen. This operation is done to inhibit all the fields to be written to (or read from). Alternatively, the end user can individually deselect a given field by using the mouse and clicking its corresponding check box. “Query” Button: Clicking on this button performs a read operation on all the fields that have their check box enabled. Once clicked, all the selected fields will be read back reflecting their current configuration. “Update” Button: Clicking on this button performs a write operation on all the fields that have their check box enabled. Once clicked, all the selected fields will be written to with the value denoted in their respective field (text box). “Store All Setup Pages” Button: Clicking on this button stores all setup pages, even if they are not shown. “CLR” Button: Clicking on this button clears out all fields on the screen, regardless of whether the fields’ check boxes are selected or not. This button proves useful when the end user wants to verify that a write operation has been correctly performed. An example scenario would be to 1) enable all fields, 2) change desired field(s), 3) perform an ‘Update’ (write) operation, 4) perform a ‘CLR’ operation and 5) perform a ‘Query’ operation. As a result of the ‘Query’ operation, the fields on the screen should all update to those values that were written during the ‘Update’ operation. “Load Group” Button: The data structure of the M2T is organized into “Groups” of selected fields. A Group contains the following fields (refer to Figure 7 above): Carrier Mode, Modulation Mode, COFDM Bandwidth, COFDM mode, Guard Interval, Modulation FEC, Video Frame Size, Video Frame Rate and Input Mode. Clicking on the ‘Load Group’ button loads the selected Group to be operated on by the M2T. A Group can be selected by selecting Group Name under the pull down text box “Group Name (16Chars)” or by its Group Number under the “Group No” pull down text box. Note: After selecting a group by either its’ group number or group name you must click on the “Load Group” button for the group to take effect. The M2T allows up to 20 group types to be stored in the non-volatile memory each with its’ own unique Group name and associated Group Number. The unit is provided with 20 established groups (see page 55 ) in which the parameters have been carefully chosen for optimal performance. The end user has the ability to change the name of a group (limited to 16 characters), and to change the parameters of the fields associated with a group. Once the group is saved (pressing the “stored all setup pages”) the default parameters of the existing group are overwritten. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 30 of 55 www.cobham.com/tcs The sequence to change the default parameters of any group or group name is as follows: First load a group by clicking on the “Load Group” button. After the group loads change the parameters as desired (group name can also be changed) and then click on the “Update” button. To save the changes click on the “Stored All Setup Pages” button. Note: Clicking on the ‘Update’ button only implements any changes made temporary (until the transmitter is re-powered). The ‘Stored All Setup Pages’ must be clicked on for the changes to be saved and stored permanently. 6.4.3 Field Definitions The fields as shown in Figure 7 of the main screen (above) are defined below in Table 2. The Table also indicates if the field is a read or a write field or both.

Only legitimate video frame rates are shown for the selected video frame size. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 31 of 55 www.cobham.com/tcs Field R/W Description Input Mode R/W Default mode is SDI (serial digital interface). Supports both HD SDI and SD SDI. User can also select ASI when there is a need to transmit an ASI stream. Analog Video TS (transport stream, video) Locked Status R/W Video input format. Desired video input format is selected from the following values: PAL, NTSC, S-video PAL, S-video NTSC, and Component Video. R Video lock status. This read-only field indicates that the M2T has line-locked onto the SD or SDI video input signal. This is not meant as an indicator of the correct video input format only that video is detected on the input and the transmitter is able to lock to it. Audio Enable R/W Analog audio or embedded SDI audio. Desired mode of operation of the audio is selected from the following values: OFF/Analog/SDI (CH 1-2, up to CH 15-16.) Audio Level R/W Choice between microphone or line level audio (only applies to analog audio) Audio Gain R/W Adjustable gain values are adjustable between 0-100 (only applies to analog audio).

This is an option that may or may not be activated. Power Level Channel Rate (Mbps) Unit Name Unit Number R/W Power level choices for the RF output are ‘HIGH’ or ‘LOW’. These levels (the amount of attenuation associated with high and low) are user defined under the ‘Configuration’ menu under sub-menu, ‘SPECIAL SETUP\ OTHERS’ R Channel rate is displayed in Mbps and is based on parameters selected such as COFDM mode, FEC and Guard Interval. See Channel Rate Guide under the HELP menu. R/W Allows the user to assign a unique unit name to the M2T. R/W Allows the user to assign a unique unit number to the M2T 6.4.4 Input Mode - Switching between SDI in or ASI in The default mode for the “Input Mode” field is SDI in. However a user can select the input mode for ASI in if there is a need to transmit an ASI stream. See Figure 18 below. If the ASI input mode is selected then other fields which are not associated with transmitting an ASI stream are disabled. For example the “Video Frame Size”, “Video Frame Rate”, “Audio Enable” and “Audio Gain” are fields which are not needed and hence disabled. Keep in mind when transmitting an ASI stream ensure the transmitter channel rate is set to at least 10% above the data rate of the input ASI stream. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 32 of 55 www.cobham.com/tcs Figure 18 – Input Mode 6.4.5 Audio Enable - Switching between Analog audio and Embedded SDI audio The M2T supports 2 analog audio channels or up to two channels of SDI embedded audio. It also supports balanced input and single ended inputs (see 5.2 and 5.1.5 for configurations supported). Under the “Audio Enable” field there are three basic selections: OFF (no audio on the Transport stream) Analog audio SDI CH 1-2 to SDI CH 15-16 (see Figure 19 below) When choosing SDI audio, selections are based the ability of the transmitter to support two audio channels. Hence depending on the parameters of the embedded audio in the SDI stream, that is which group is activated (1 to 4) and which audio channels are activated (1 to 16) the user is able to select up to two channels (SDI CH 1-2 to SDI CH 15-16) to place on the Transport Stream. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 33 of 55 www.cobham.com/tcs Figure 19 – Audio Selection 6.4.6 Pull-Down Menu Definitions There are several different pull-down menus that are included in the M2T Configurator program.

When the “Encoder Only” mode is selected an internal clock source (from the encoder module itself) is used as the source. The bit rate is limited from 6 to 70 Mbps. The encoder module can be used as a standalone module encoding rates up to 70 Mbps using the ASI out (J2) port of the M2T. This Transport Stream does not include the SI tables, User-Data, or AES encryption which is added later in the processing chain. Note: If the transmitter is suspected of having RF interference the user can test the encoder section of the M2T by attaching a cable from the ASI port (J2) to a decoder ASI input port directly. GOP Length - User can select GOP (Group of pictures) length when in Normal mode only .Choices includes 10, 20, 30, 40 or 50 GOP. In Ultra-low delay mode there are no choices. Video Delay Mode – User can select from two different delay modes involving different tradeoffs: Normal – this mode gives the best picture but the delay is longer than the other two modes however it can be used with commercial decoders. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 37 of 55 www.cobham.com/tcs Ultra-Low – this mode is the default mode and can only be used with Cobham Tactical Communications & Surveillance Tactical Communication & Surveillance HD decoder.

High Power Att (0-12dB) - When in high power mode the RF attenuator range is 0 to 12dB, attenuated in 1 dB increments. COFDM Spectrum Inversion – Choices include normal or inverted. The transmitter is configured with the receiver it ships with and the inversion mode does not require changing. However if a different receiver is used the inversion mode may be required to be changed. Some receivers will accept either inversion modes. RF Power Mode – Can be used to put the Transmitter in a Sleep Mode, where the Encoder functions and many of the Power Regulators are shut down enabling a saving in current (approx. 40%) when the Transmitter is not active. Group Switches – This setting has no function in the M2T-C. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 41 of 55 www.cobham.com/tcs Figure 29 – Others 6.4.6.2.2 Transport Stream The transport stream menu (reference Figure 30) displays the parameters of the current transport stream (of the transmitter). The fields are read/write-able. Normally the fields require no manipulation and should work quite well as defaulted from the factory. However, high end users may have a need to change the transport stream parameters. Entry of information into this screen’s fields can be done in either decimal or hexadecimal. Hexadecimal is specified by a “0x” prefix. The information is always displayed in hexadecimal. The 13-bit packet ID (PID) values are limited based on the selection of the Carrier Mode from the main screen. In the 2 k carrier mode, the PIDs are limited from 0x020 to 0x1FFE. In the 4k carrier mode, the upper limits of the PIDs are restricted to 0x00FE. These limitations are available to the user in the form of tool tips that can be displayed by hovering the cursor over the associated entry field. In addition the NIT (network information table, PID 0x0010) and the SDT (service description table, PID 0x0011) are also added to the Transport Stream when transmitting out through the RF port. These two tables are not added when using the ASI stream (ASI OUT-BNC connector) out of the transmitter. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 42 of 55 www.cobham.com/tcs Figure 30 – Transport Stream Setup TS Version Number, Video Stream ID, and Audio 1 Stream ID are not currently changeable. 6.4.6.2.3 Ctrl Port Baud Rate The control port baud rate menu allows different baud rates to be selected.

D/C (Down Converter) IF frequencies explained 8.1 IF Frequencies MSR receivers (and many other digital receivers) are capable of receiving direct frequencies in the range of approximately 49 MHz to 861 MHz. If the transmitter is not in this range then a downconverter (also refer to a BDC, block down converter) is used to convert the frequency to this range. The frequency out of the down-converter is called the IF (intermediate frequency) which is fed to the receiver. Down-converters have a LO (local oscillator) which is mixed with the transmitter frequency (M2T) and converts it to the IF frequency. MSR receivers need to know the LO (local oscillator) of the downconverter and the RF frequency of the transmitter. It then automatically calculates the IF frequency. The IF frequency changes as the RF frequency changes,. However, the LO remains constant. On non- Cobham Tactical Communications & Surveillance receivers it may be necessary to program the receiver with the IF frequency directly. The user may have to do the simple math to arrive at the IF frequency so that it can be entered into the receiver. The down-converter LO must be known. The math involve is as follows: “LO – transmitter frequency (or transmitter frequency – LO) = IF frequency”. For example, it the transmitter is set for 2000 MHz and the LO of the down-converter is 2800 MHz then the IF frequency is 800 MHz (2800-2000 = 800). The receiver will need to be set to 800 MHz to receive the transmitter frequency of 2000 MHz. Each time the transmitter frequency is changed the IF must be re-calculated and entered into the receiver. It must also be mentioned, as you may have noticed with the equation “LO-transmitter frequency or transmitter frequency – LO” that two answers are possible. For example 2800-2000 = 800 or 2000-2800 = -800. The negative answer may indicate the receiver wants the signal to be inverted. See section 6.3.3.2 for inverting the signal. 8.2 Local and Remote Power for Down Converters Customers have the option of using remote or local power. 8.2.1 Remote Power Remote power is provided from the MSR through the BNC connector from each of the tuners located on the rear panel. Power is turned on through the software control application (refer to the MSR online manual). The +12 Vdc provided from the receiver will travel through the coax cable to the D/C. If the D/C is located relatively close to the receiver then using remote power makes sense. However, if the D/C is located at great distances away from the receiver there may be excessive DC voltage drop in the coax cable (due to cable resistances). If this is the case then local DC power should be considered as discussed below. If unsure of the DC voltage drop measure the DC voltage present (using a DMM) at the end of the coax cable run; the D/C normal operating voltage is approximately +12 Vdc but can operate down to +10 Vdc. 8.2.2 Local Power Local power is provided by applying +12 Vdc to pin 1, GND to pin 3 of the DB-9 connector located on the bottom of the D/C. The +12 Volt power supply must be able to source at least 500 mA. The power switch (located on the side of the D/C) enables the user to control the ‘ON’/’OFF’ positions for local power. If using local power then the remote power should be set to “OFF”. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 50 of 55 www.cobham.com/tcs Figure 35 – BDC Connectors Table 3 – DB-9 Connector Pin Out for the D/C Pin Signal 1 +12 Vdc 3 2, 4-9 GND NC Notes Power supply must be able to source at least 500 mA.

Cable Losses 9.1 Coax Cable Cable losses must be taken into consideration if the D/C is located a great distance from the receiver. As mentioned above long cable runs can contribute to more resistance in the lines and also can contribute to signal attenuation because of the additional capacitance. Even when using a good coax cable such as RG59/U the attenuation of the signal can be significant. For example, RG59/U coax will drop approximately 2 dB per 100 feet at 50 MHz and 8 dB per 100 feet at 900 MHz. The intermediate frequency (IF) in this system can fall between 49 MHz to 850 MHz. An inline amplifier matching the cable losses should be considered if losses exceed 6 dB. 100-M0084X3 GMS INC. doing business as Cobham Tactical Communications and Surveillance 52 of 55 www.cobham.com/tcs 10. Fan Filter Maintenance At least twice a year the filters for the two external fans should be cleaned. The recommended procedure is to use compressed air, blowing through the fans in the direction indicated, see Error! Reference source not found. below. The debris exits through the cooling fins as shown. Don’t use excessive air pressure, start with a reasonable setting, around 30 PSI and increase as necessary to clean the filters noting that excessive pressure may damage the fan housing or the fans.
